cyrtranslit 1.0.1

Transliterate Cyrillic script to Latin script and vice versa.

What is CyrTranslit?

A Dart package for bi-directional transliteration of Cyrillic script to Latin script and vice versa.

By default, transliterates for the Serbian language. A language flag can be set in order to transliterate to and from Bulgarian, Montenegrin, Macedonian, Mongolian, Russian, Serbian, Tajik, and Ukrainian.

What is transliteration?

Transliteration is the conversion of a text from one script to another. For instance, a Latin alphabet transliteration of the Serbian phrase "Мој ховеркрафт је пун јегуља" is "Moj hoverkraft je pun jegulja".

Citation

This package is based on the Python project cyrillic-transliteration which was originally authored by Open Data Kosovo.

How can I contribute?

You can include support for other Cyrillic script alphabets. Follow these steps in order to do so:

1. Create a new transliteration dictionary in the mapping.dart_ dictionary.
2. Watch out for cases where two consecutive Latin alphabet letters are meant to transliterate into a single Cyrillic script letter. These cases need to be explicitly checked for inside the lat2Cyr() function in transliterator.dart.
3. Add test cases inside of cyrtranslit_test.dart.
4. Update the documentation in the README.md.
5. List yourself as one of the contributors.

Before tagging a release version and deploying to pub.dev:

1. Update the version properties in pubspec.yaml.
